Ua ntej, hom thiab siv mortar
Mortar yog hais txog cov khoom siv hauv tsev uas sib xyaw nrog cov khoom siv xws li cement, txiv qaub, xuab zeb thiab dej hauv ib qho kev faib ua feem. Raws li qhov sib txawv ntawm cov cement, nws feem ntau muab faib ua cov mortar zoo tib yam, lub zog qib mortar thiab mortar tshwj xeeb.
1. Ordinary mortar feem ntau yog siv rau lub tsev phab ntsa thiab plastering phab ntsa;
2. Lub zog qib mortar yog tsim rau kev tsim kho tej yaam num uas yuav tsum tau muaj zog dua;
3. Cov mortar tshwj xeeb yog tsim rau ntau yam kev tsim tshwj xeeb, xws li suab rwb thaiv tsev mortar, thermal rwb thaiv tsev mortar, thiab lwm yam.
Qhov thib ob, cov teeb meem tshwm sim thiab kev daws teeb meem ntawm mortar
Cov teeb meem tshwm sim hauv cov txheej txheem mortar muaj xws li tsis muaj zog adhesion, tawg, qhov chaw tsis sib xws, thiab lwm yam. Nov yog qee qhov kev ua haujlwm:
1. Tsis muaj zog cohesion: Nws tuaj yeem tshwm sim los ntawm qhov tsis raug mortar proportions, kev tsim kho tsis zoo, kev kho tsis zoo ntawm lub hauv paus txheej, thiab lwm yam kev daws teeb meem yog sib xyaw kom raug, ua kom cov dej txau thiab humidification thiab lwm yam kev ua haujlwm kom ntseeg tau qhov zoo ntawm cov khoom. mortar.
2. Kev tawg: Nws tuaj yeem tshwm sim los ntawm cov txheej txheem tsis muaj zog lossis lub sijhawm tsis muaj mortar hardening. Txoj kev daws teeb meem yog los kho lub hauv paus txheej los xyuas kom meej tias lub hauv paus txheej yog du thiab ruaj, thiab tib lub sij hawm them sai sai rau lub sij hawm hardening ntawm mortar.
3. Qhov chaw tsis sib xws: Qhov no tej zaum yuav yog vim qhov kev tsim kho tsis raug, xws li kev txhuam tsis sib xws, thiab lwm yam kev daws teeb meem yog ua tib zoo tshuaj xyuas lub hauv paus txheej ua ntej kev tsim kho, xyuam xim rau lub thickness thiab uniformity ntawm daim ntawv thov.
